Analysing and transcribing the original 75-year old V2 rocket turbopump technical drawings for modern 3D modelling systems. Computer Aided Design (CAD) has a surprisingly long history but the modern 3D CAD we see everywhere today did not take root until […]
About ten years ago now I was shown a relic, found in the sandy soil of the Peenemünde woods, that turned out to be part of a simple system for evaluating the fuel injector inserts used in the 25-ton test […]
With a few notes on the development history of this critically important technology The time boundaries for the development of the fuel injection system of the A4/V2 25-ton thrust engine are simple enough to state; the process began at the […]

In this video we take a closer look at the propellant injector nozzles used on the A4 / V2 rocket. The world’s first ballistic missile and progenitor of all space exploration rockets employed a fuel and liquid oxygen injection system that consisted of complicated 18 pot, so-called, pre-mixer system using large numbers of ‘swirl’ nozzles in each pot. The system was only a prototype, a stop-gap, while an optimised version was developed. But the death of lead designer Walter Thiel in an air raid and the severe pressure to employ the V2 in combat as quickly as possible forced the designers put this steeply compromised prototype injector head into production. In this video, we look at the injectors used in the V2’s 18 pot head in detail and even test the mix patterns and flow rates of some of the injector nozzles. Presented by Robert J Dalby FRAS
